We Detected surface area N on equally contaminated cells and non-infected neighboring cells24. N, like all N proteins, is highly positively charged, and binding of endogenous N and cell-derived or recombinant N to cells needs heparan sulfate/heparin (hugely negatively charged proteoglycan), as demonstrated via the abrogation of binding by enzymatic https://silica-coated-magnetic-be82581.anchor-blog.com/9920748/how-much-you-need-to-expect-you-ll-pay-for-a-good-magnetic-beads-for-dna-purification
